从专利角度分析国内外喷气涡流纺的发展
Development of Vortex Spinning at Home and Abroad from Patent View
摘要
Abstract
The development process of vortex spinning at home and abroad was discussed from patent view.Related patents about vortex spinning at home and abroad were searched and analyzed from every search platform.Quantity,quality and applicant distribution of patent at home and abroad were compared.Development state,technology focus and quality of vortex spinning at home and abroad were summarized.It is considered that twist device,joint device and draft device of vortex spinning are researched as key points at abroad.At home key points of the study are how to improve the quality of vortex spinning yarn and how to extend the range of raw materials through pre-treating.Vortex spinning research started late at home,there are certain gaps at license and effective rate of patent comparing with related patent at abroad.关键词
